I think it is not necessary to explain the meaning of such terms as machine learning and artificial intelligence in 2017. You can find a lot of op-ed articles and research papers on this topic. So, I assume that the reader is familiar with the topic and knows definitions of basic terms. When talking about machine learning, data scientists and software engineers usually mean deep neural networks that became quite popular because of their productivity. So far there are many software solutions and packages for solving artificial neural networks tasks: Caffe, TensorFlow, Torch, Theano(rip), cuDNN, etc.

Swift

Swift is an innovative protocol-oriented open source programming language written within Apple by Chris Lattner (who recently left Apple and, after SpaceX, settled down in Google).
Apple OS already features different libraries for working with matrices and vector algebra, such as BLAS, BNNS, DSP, that were later on gathered in the single Accelerate library.
In 2015, small-scale solutions based on the Metal graphics technology for implementing math appeared.
In 2016, CoreML was introduced:

CoreML

CoreML can import a finished and trained model (CaffeV1, Keras, scikit-learn) and allows developer to export it to an application.
So, in the first place, you need to prepare a model on another platform using the Python or C++ language and third-party frameworks. Second, you need to educate it using a third-party hardware based solution.
Only after that you can import it and start working with the Swift language. As for me, it all seems too complicated.

You should know, that TensorFlow written on C++ as core (backend) and Python as frontend languages.

Python was the first client language supported by TensorFlow and currently supports the most features. More and more of that functionality is being moved into the core of TensorFlow (implemented in C++) and exposed via a C API.

If you are working with TensorFlow not only as Python software engineer, from time to time you should use C++ environment and available code, in your work. Sometimes you need to clarify C API, sometimes use it to port Python available code to other language. Any way you have to have build – ready C++ code on your computer.

How you can prepare it?

Since today Kraken is high – level API and brain system for the most powerful deep – learning framework TensorFlow.

TensorFlow is the fastest growing solution for neural networks. Written on C++ language it shows huge performance on CPU and GPU hardware. Kraken could help us to build deep learning architecture at real time and test them in different ways and on different servers.

Using TensorFlow library as core of our Neural Network you can get lot’s of benefits as:

Each machine learning task is related with big amount of data. Analyzing a network is a complex and confusing task. To resolve that issue, Google announced launch of visualization tools called TensorBoard.

Currently that is the most useful source-code tool. Unfortunately that tool works only with TensorFlow library from the box. There is no way to feed it with json or xml logs.

Deepening into a self-written neural network you can’t avoid any data-visualization task. For that reason you can use Tensorboard from C/C++/Java or Swift application.
